Let the silly season commence with this expensive comic-book movie, which takes full advantage of its second-tier superhero, free casting rein and Asgard-sized budget to deliver some premium disposable spectacle. Hemsworth's beefy, impetuous thunder god is literally brought down to earth, where thanks to mortal hotties like Portman, he learns there's more to life than swinging a hammer around, but not much more.

The corruption of Helms's naive smalltown nerd via a debauched midwest insurance convention is as broadly amusing as you'd expect, striking a filthy-sweet tone somewhere between the US Office and The Hangover.

Another dark and brutal revenge thriller in what's becoming a grand Korean tradition. This one sees agent Lee hunting down the psycho who killed his fiancée (Old Boy's Choi), and by no means letting him off lightly.
